This will ship with a tune for stock speakers. Later if you upgrade, they will help you set up your new speakers by tuning remotely. Great people to work with.
I also added a Kicker self powered sub woofer mounted in the stock...
I usually just get a Motorcraft filter from Amazon. I've tried K&N oil filters twice and both times the supplied o-rings were brittle and broke when installing.
You can get them with the opening covered that protects just as well if not more so than the stock step. The slider extends a little farther then stock.
So people thing frame mounted sliders won't flex with a pivot point 18 or so inches from the point of impact? That's cute. The extensions from the frame to the slider will hit the sill.
I'll say it again, people are putting to much emphasis on frame mounted sliders. Actually get under your truck...
